FiLM-WINDING Mncrmmsivn Specification of Letters Pat i To'all @ahoga/z?mayy concern.' `Be it K 'own that I, PAUL C. BRnNNER,.a'

citizen ofj'the United States, residing'at' "Chicago,A in the county of Cook and State of Illinois, have invented new and useful Im-. prpvements in 'Film-Vinding Mechanism, of which' the followinf is a specification.

IThis invention relates to iilmlwinding) mechanism vfor motion picture apparatus; and Jit has for its primary v.object the previsi'on of means for winding. the film from thedelivering magazine ito the receiving magazinein 'such manner that the front end ofthe film-will .be always arranged outermost `so that thecomplete coil' of iilm can be eratively arranged in the delivering magazine for an immediateA re'xhibition and ing injury to. the iilm during the winding lof the film.

Another obj ect-of the invention is the provision of 'film windingmcchanism wherein the iilm on its delivery tothe winding or receiving' magazine may be initiallyv drawn by induced suction toa position to permit vof an accurate rewinding-Of the film. .Another obj ect ofv the invention is the provision of vfilm winding mechanism which wil-l be constructed with' a view to eliminating injury to the. film during the rewindin'g operation. l LA further v"object of tthe invention is the provision of a receiving magazine which -will vvinclude a re'vo'l'vingv 'driven tray .and means for operating the tray.` directly '-tlinough the controllingmechanism 4of the picture exhibiting machine whereby to ne tces's'si-tate an immediate :stoppage' of the tray .when vthe .picture exhibiting machine,` is',

thrown out of operation, such as atthetin'fie off ya break in the film.

Another object of the invention is :the ,provision Iof a yreceiving tray which will :be adf justable so as to accommodate itself to films Vo ffdiii'erent lengths.

' A still further Iobject 'of the invention is. the provision of means for .facilitating theoperation of removing the mewound iilm from the receiving't-ray. l

and Fig. Gis 'a side view of the-receiving magazine, showing `the outer casing partly removed and exposingthe perforated walls of the rewinding tray.-

j vThe' picture exhibiting machine 'shown conventionally herein at A may be of the usual well known type, and-is shown to linclude a vdriven shaft B for operating the machine to `draw the iilmintermittently over v the framing 'or exhibiting opening in lthe usual ina-nner. The delivering magazine C is preferably mounted vertically upon the machine A, and it is provided with a-driven spindle D, on which-is mounted a reel E consisting of separable sections F and 'G whereby to facilitate the `operation of apl plying vtheroll or coil of -ilm prior to the display of the pic-tures.

The exhibiting machine A is mounted on a platiiorm I and supported. from beneath the I"platform isa fan casing JJ having a revolubly vmounted. fan Kv therein for apurpose to-be hereinafter explained. The supporting shaft vof lthe fan is connected by means of 'a belt L with the driven. shaft of the 'picture exhibiting machine, so `asto be directly driven thereby when the' Amachine fi-s in operation and to' be instantly stopped whenl the tion. l

The receiving magazine comprises. a

machine is throw-n out of operaveasing 1"mounted'upon the platform 1 and at right 'angles tothe :axis ofthe delivering magazine .of fthe picture exhibiting machine.

This casing is provided with annular `vertically rising walfls '2, to which is removably ffntted a. transparent coverr of plate-glass, said cover having annularI-met-a-l rim 4, 'whichis provided with a depending flange 5 vwhich embraces the vertical walls 2 of the casing l when the cover is applied. At the` ioo center .the cover is provided with a relatively.

large guide opening :6. .The platform l supportsa driving shaft?? ,which is connected Aat 8 lwith [the picture exhibiting machine so 'thatwhen the latter is in operation, pewer f i120 are: adapted to lhold the adjacent terminals bei-transmitted to the'. shaft for a ,pur- `v` pose to be hereinafter explained. The receiv'ing tray 8 comprises a horizontal'bottom .9 secured atits center to theshaft f7, a-

spacing4 Washer 10 being interp'osedfbetween the bottom of thecasing 1 and the bottom 9 of the tray 8', so as to hold the bottom 9 out of frictional contact with the bottom of the i casing. This trayably accommodating the side walls 12 of theis provided with concentric continuous grooves 11ifor 1nterchange tendedtlirough receiving passages M .in the other. end of the strip according t`o the adjustment'desired to a proper accommodation v extended bevond the upper e the tray of a film ofA aprescribed length. Clamping nuts 15 are associated with the studs13, and

of the 4wall forming strip properly connected with each other. p' The/walls 12are provided with perforatins 16,'. which open yinto the film recei-vingspace of the tray -and which open alsoI into-the annular space 17 between and the vertical walls 2 of the Casin 1. The bottom 9 ofthe tray isprovided at suitable intervals with vertically rising springs -18 having their upper ends ges of the tray 8""and then ybent inwardlyv at 19 and then upwardly at 20 and then outwardly at 21 so as to form a retainer which is adapted to engage .against the edge of a transparent cover 22, the latter being removably mounted upon .the tray 8', as clearly shown in Fig.

The cover 22' is also constructed of plateglass and is provided with a relatively large nopening 23 which is located directly beneath the opening 6 in the cover 3 of thecasing 1. In order that-suction may be created in the space 17 andin the -tray 8 I connect the suction fan with the walls 2 of the casing 1 by branch pipesv 24.-

Y From the construction described, it is evi-A dent that the -front end of the lm, after being'passed through the` picture exhibiting, Amachine may be'v extended over a suitable.-

g'uidefpulley 25v upon ythe platform I. and then extended'through the alinedV openings 6 and 23 and arranged in the tray 8, so that l tively of .the outer walls of the revolving Simultaneously with this operation,

as soon" as the exhibiting machine is set in operation the suction fan will hev also operate'dand the air drawn Jfrom the 'outside in .thev direction of the arrows indicated in Fig. 3 and suction directly applied to the nrst-terminal'or front end of the film'A and to thereby .automatically draw said front endy into .a proper Winding position relatray 8. .the tray isl also revolved and the film is drawn continuously from the delivering lmagazine of the picture exhibiting machine machine for further exhibition, VLin iderstood. In order to increase 'thel appli- "cati'on of the suction against th'ez'lm the bottom 9v is preferably provided with aseries and wound 1n a compact manner and arranged so that it may be removedv from the tray with facility' and immediately laced backupon the reel of the picture exhi iting as will. be

of radially extending grooves 26, as shown.

Vhile the apparatus is,` particularly de signed- ;tor the use hereinbefore specied, it

is tobe understood that it may be used advantageously Vfor Windingribb'onatapes, or

4 -The arrangement' of the tray andthe connection vtherewith of the surrounding casing pis such that the first convolution ofthe film will'be drawn in an .outward direction and immediately against the Walls `of the 'casing lwhere afvacuum is formed and said outer 'portion of the film held in a relatively fixed position. After this* operation the air is drawn through the openingin the casing and through the opening in the ,trayland' through induced suction toy the -other wound portions of the nlm are drawn outwardly and against the first portion, the air enter-- ing the radial grooves'ii the 4bottom of the tray so as to operate directly against'the edges of the nlm asfyvill be'understood.

From-the foregoing description, taken in connection Awith ,the accompanying drawings, the construction and operation ofthe invention will be readily understood with'-`A` out requiring a more extended explanation.-

Various changes in the form, proportion 'and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as claimed.

` Having thus described my invention, what Iclaim is:'- f .1. `The combination with a moving picture apparatus, of la revolvin means operatedby theexhi iting apparatus for revolving the receiver, and means operated by the apparatus for inducing suction 1in the receiver. ,radially of the axisl thereoi'.
